limits.h - implementation-dependent constants
</blockquote><h4><a name = "tag_000_007_348">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

#include &lt;limits.h&gt;
</code>
</pre>
</blockquote><h4><a name = "tag_000_007_349">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>&lt;limits.h&gt;</i>
header defines various symbolic names.
Different categories of names are described below.
<p>
The names represent various limits on resources that the
system imposes on applications.
<p>
Implementations may choose any appropriate value for each limit, provided it
is not more restrictive than the Minimum Acceptable Values listed below.
Symbolic constant names beginning with _POSIX may be found in
<i><a href="unistd.h.html">&lt;unistd.h&gt;</a></i>.
<p>
Applications should not assume any particular value for a limit.
To achieve maximum portability, an application should not require
more resource than the Minimum Acceptable Value quantity.
However, an application wishing to avail itself of the full amount of
a resource available on an implementation may make use of the value given in
<i>&lt;limits.h&gt;</i>
on that particular system, by using the symbolic names listed below.
It should be noted, however, that many of the listed
limits are not invariant, and at run time, the value of the limit may differ
from those given in this header, for the following reasons:
<ul>
<p>
<li>
The limit is pathname-dependent.
<p>
<li>
The limit differs between the compile and run-time machines.
<p>
</ul>
<p>
For these reasons, an application may use the
<i><a href="fpathconf.html">fpathconf()</a></i>,
<i><a href="pathconf.html">pathconf()</a></i>
and
<i><a href="sysconf.html">sysconf()</a></i>
functions to determine the actual value of a limit at run time.
<p>
The items in the list ending in _MIN give the most negative values that the
mathematical types are guaranteed to be capable of representing.
Numbers of a more negative value may be supported on some systems,
as indicated by the
<i>&lt;limits.h&gt;</i>
header on the system, but applications requiring such numbers are not
guaranteed to be portable to all systems.
<p>
The Minimum Acceptable Value symbol * indicates that there is no
guaranteed value across all XSI-conformant systems.
<h5><a name = "tag_000_007_349_001">&nbsp;</a>Run-time Invariant Values (Possibly Indeterminate)</h5>
A definition of one of the symbolic names in the following list will be
omitted from
<i>&lt;limits.h&gt;</i>
on specific implementations where the corresponding value is equal to or
greater than the stated minimum, but is indeterminate.
<p>
This might depend on the amount of available memory space on a specific
instance of a specific implementation. The actual value supported by a
specific instance will be provided by the
<i><a href="sysconf.html">sysconf()</a></i>
function.
